Atypical full-field digital mammographic findings of breast cancer / 中华放射学杂志

ABSTRACT

Objective To evaluate the diagnostic significance of full-field digital mammography (FFDM)for atypieal breast cancer findings.Methods Seven hundred-eighteen cases with breast cancer were examined using FFDM and atypical mammographic findings were found in 134 cases.Craniocaudal (CC)view and mediolateral oblique(MLO)view were conducted for each patient.Mediolateral view or spot view Was achieved if necessary.Preoperative localization Was conducted for the patients with nonpalpable breast cancer8.Results (1)The masses with well.circumscribed margin on mammography were more common in infiltrating duetal carcinoma(22/106),mucinous carcinoma(8/10),medullary carcinoma (5/6),and increased with age and reduction of the mass density.(2)Long spieulation,architectural distortion,patchy high density were mainly found in infiltrating ductal carcinoma and 30-40(24 cases),41-50(34 cases)years old patients.Long speculation wag mainly found in 30-40 years old patients (10/30).(3)Hish homogenous density and subcutaneous edema in the entire breast and mass-like area were most ffequendy found in infiltrating ductal carcinoma at 30-40(2 cases)and 41-50(5 cases)years old.High density and subcutaneous edema were only found in dense breast(8 cases).Conclusion The atypical findings of breast cancer in foil-field digital mammography are associated with the pathological type of cancer.patient age and the gland density of the breast.
